Geant4 9.4 - patch-03 Release Notes
3+
-----------------------------------
4+
5+
9 December 2011
6+
7+
List of fixes included in this public patch since the public release 9.4.p02:
8+
9+
o Configuration:
10+
-------------
11+
+ Darwin-g++.gmk: modified OGLLIBS settings for proper configuration of
12+
OpenGL libraries in combination with Qt. Allow use of Qt libraries not
13+
installed as Framework. Also addressing problem report #1267.
14+
Removed unnecessary 'gcov' linkage for dynamic libraries.
15+
+ G4UI_BUILD.gmk: added setting of G4INTY_BUILD_XT for OPENGLXM and OIX.
16+
Visualization drivers need Xt, so this covers the case when the user
17+
does not build Xt from G4UI_BUILD flags. Addressing problem report #1250.
18+
19+
o Digits_Hits:
20+
-----------
21+
+ G4THitsMap: removed the print-out of total value, to avoid inconsistency
22+
caused by a class <T> which does not have += operator or cannot be
23+
initilized to 0. Addressing to the problem report #1258.
24+
+ Fixed some Coverity defects for uninitialised pointers in
25+
G4TDigiCollection and G4THitsCollection.
26+
27+
o Error Propagation:
28+
-----------------
29+
+ Defined method GetTranfMat() in G4ErrorFreeTrajectoryState.
30+
Addresses problem report #1248.
31+
32+
o Geometry:
33+
--------
34+
+ divisions:
35+
o Optimise initialization of phi angles in parameterisation for tubs
36+
and cons.
37+
+ magnetic_field:
38+
o Corrected computation of 'omegac' G4EqEMFieldWithEDM, G4Mag_SpinEqRhs
39+
and G4EqEMFieldWithSpin with more coherent formula. Simplified formula
40+
for computation of kinetic energy in G4FieldTrack.
41+
+ navigation:
42+
o Fix in locator classes and navigator to address cases of tracks stuck
43+
on boundary of volumes: improved the condition for accepting a
44+
candidate intersection with a boundary in all locator classes, now
45+
checking if the track enters in the new volume.
46+
Resolves long-standing issue reported by ATLAS.
47+
+ solids/Boolean:
48+
o Corrected protection in G4SubtractionSolid::DistanceToIn(p,v)
49+
introduced previously and relaxed to not cause event abortion.
50+
+ solids/CSG:
51+
o G4Sphere: fix for setting of relative radial tolerances when setters
52+
for radiuses are explicitely called (affecting parameterisations on
53+
radius for spheres).
54+
Relaxed validity condition in construction for the minimum size of the
55+
outer radius.
56+
+ solids/specific:
57+
o Fix in G4TriangularFacet::Intersect() to take into account geometrical
58+
tolerance and cases of zero distance from surface's facet; fixed tests
59+
where square root was compared to half Cartesian tolerance; now
60+
compared to kCarTolerance. Addressing problem report #1242.
61+
o Fix in G4TessellatedSolid::DistanceToOut(p) and DistanceToIn(p) to
62+
exactly compute distance from facet avoiding use of 'outgoing' flag
63+
shortcut variant. Addressing problem report #1242.
64+
o Fix in G4Paraboloid::DistanceToIn(p,v) and DistanceToIn(p) to properly
65+
take into account tolerance and provide better estimation of distance
66+
respectively. Addresses problem report #1234.
67+
o Fix in G4EllipticalCone in DistanceToIn(p,v) to exclude imaginary
68+
solution (virtual cone) when distance is calculated.
69+
o Defined SetReferences() and InvertFacets() to
70+
G4GenericTrap::CreatePolyhedron() for proper visualisation of Boolean
71+
compositions with G4GenericTrap.
72+
o Defined SetReferences() to G4TessellatedSolid::CreatePolyhedron()
73+
for proper visualisation of Boolean compositions with
74+
G4TessellatedSolid. Addresses problem report #1235.
75+
o Fixed logic in G4VTwistSurface::GetEdgeVisibility() in treatment of
76+
corners.
77+
+ volumes:
78+
o Use WIN32 instead of G4LIB_BUILD_DLL as flag for protecting allocator
79+
choice in G4NavigationHistory on Windows.
80+
81+
o Global:
82+
------
83+
+ Added missing post-const qualifier to G4String::compareTo() methods
84+
+ Changed date for patch-03 to release 9.4.
85+
86+
o Graphical Representations:
87+
-------------------------
88+
+ G4PolyhedronArbitrary: defined SetReferences() and InvertFacets() methods
89+
necessary at the end to complete the polyhedron, in particular if the
90+
polyhedron suffers subsequent Boolean operations.
91+
+ Consistently make use of G4 types in HepPolyhedron and BooleanProcessor.
92+
93+
o Persistency:
94+
-----------
95+
+ ascii:
96+
* Fixed case of dereferencing null pointer in G4tgbGeometryDumper
97+
DumpRotationMatrix() method.

107+
o Removed include of unused header in G4GammaConversionToMuons.
108+
+ Standard:
109+
o G4CoulombScatteringModel, G4eCoulombScatteringModel: increased
110+
low-energy threshold from 1 eV to 1 keV, below this threshold
111+
particle energy is set to zero
112+
o G4UrbanMscModel90, G4UrbanMscModel92, G4UrbanMscModel93: added
113+
protection for sampling of angle for very small steps and high
114+
energy e-. Fixing rare cases of back-reflection.
115+
+ Utils:
116+
o G4EmModelManager: fixed bug in algorithm to smooth cross-sections
117+
between different models. Responsible for observed discrepancy in
118+
lateral shower shapes reported by CMS.
119+
+ Xrays:
120+
o G4SynchrotronRadiation, G4SynchrotronRadiationInMat: fixed length
121+
of C-arrays for the interface with EM field.
122+
Addressing problem report #1236.
123+
o Fixed compilation warnings for variables set but not used.
124+
Fixed some Coverity defects.
125+
126+
o Hadronic Processes:
127+
------------------
128+

129+
o G4ElectroNuclearCrossSection: protections to avoid FPE numerical
130+
problems at low energies
131+
+ management:
132+

133+
second cross-section (avoid computation of cross-section for zero
134+
energy particles).
135+
+ models/cascade:
136+
o G4CascadeInterface: added protection for proton target conservation
137+
failures. These happen due to elastic scattering near threshold.
138+
139+
o Generic Processes:
140+
-----------------
141+
+ Parameterisations/gflash:
142+
o Fixed bug in G4FlashShowerModel::ModelTrigger() for energy condition.
143+
o Fixed Coverity defects, mainly related to uninitialised static data.
144+
+ Transportation:
145+
o Modified calcuation of 'deltaTime' for optical photons in
146+
G4Transportation (and G4CoupledTtansportation). The final velocity
147+
obtained by G4Track CalculateVelocityForOpticalPhoton() should be
148+
used instead of the initial velocity of the step.
149+
Addressing problem report #1239.
150+
151+
o Track:
152+
-----
153+
+ Fix problems related to treatment of weight in G4ParticleChange.
154+
Addressing problem report #1243.
155+
+ Use G4VelocityTable as singleton to avoid unnecessary creation of
156+
G4PhysicsVector objects in the event loop.
157+
158+
o Examples:
159+
--------
160+
+ Updated reference outputs.
161+
+ extended/parameterisations/gflash
162+
o Fixed bug in ExGflashSensitiveDetector::Initialize() for creation of
163+
new hits collection.
164+
+ novice/N04
165+
o Optimised initialisation of Phi angles in parameterisations to avoid
166+
recomputation of trigonometry.
167+

8+
9+
o Geometry:
10+
--------
11+
+ Magnetic Field:
12+
o G4FieldTrack: added inline method to set the Rest Mass. Needed in
13+
order to reset this and keep reuse the same G4FieldTrack in a
14+
client across tracks.
15+
16+
o Global:
17+
------
18+
+ G4Pow: reduced vector for factorial from 512 to 170 (result should be

42+
o G4QCaptureAtRest: added check on 4-momentum balance for violations
43+
of more than 2 GeV; repeat sampling again. Check baryon number of
44+
final state and take into account nuclear recoil at rest which is
45+
not produced as a final particle.
46+
47+
o Track:
48+
-----
49+
+ Fix to reset 'RestMass' in G4FieldTrackUpdator::Update() method
